CAR-FRAME.

SPECIFICATION forming part of Letters Patent No. 785,866, dated March28, 1905.

- Application filed January 29, 1904. Serial No. 191,117.

To (all whom it ntcty concern.-

Be it known that I, ETHAN I. Donns, of Avalon, Allegheny county,Pennsylvania, have invented a new and useful Oar-Frame, of which thefollowing is a full, clear, and exact description, reference being hadto the ac companying drawings, forming part of this specification, inwhich- Figure 1 shows in vertical cross-section a car-frame constructedin accordance with my invention. Fig. 2 is a vertical longitudinalsection on the line II II of Fig. 1. Fig. 3 and Fig. 4 are sectionssimilar to Fig. 2, but illustrating modifications of the invention.

My invention is an improvement upon the invention described and claimedin an application, Serial No. 191,116, filed herewith, (Case A and inthe main the improvement consists in using, instead of the strut-barsshown in the drawings of that application a strut-plate which extendsupwardly from the web of the bodybolster. The plate which I use servesas a tension member for the body-bolster and also as a connectionbetween the bolster and the car-floor.

In the drawings, 2 is the center sill of the car, which is preferablymade of parallel channel-beams, as shown in Fig. 1, but may be otherwiseconstructed.

3 3 are the members of the body-bolster, which extend at right angles tothe center sill and are fixed thereto at their inner ends with theirupper edges extending above the level of the center sill. These membersare preferably formed with an integral flange at their lower edge andwith an unflanged upper edge. This can be done by taking an I-beam, asshown in Fig. 2, and shearing it longitudinally with a bias cut throughthe web, or taking a channel-beam, as shown in Fig. 3, and shearing itin like manner, reinforcing the remaining flange by an attached angle orother flanged section 4, or the bolster may be constituted by twosections cut with a longitudinal bias cut from a channel, bar and setback to back, as shown by the parts 3 in Fig. 4. The bolster constitutedas shown in these figures is connected with the car-floor 5 by aninterposed strut-plate 6, which is riveted to the part of the bolsterprojecting above the center sill and is also riveted to the car-floor.The connection be tween these parts is preferably reinforced and theconstruction rendered stiffer by braces 7, which connect the web of thebolster with the plate and are riveted to each. Some of these braces arediagonal, and thus distribute the load advantageously. I show them inthe drawings as consisting of anglebars; but they may be formed ofchannels. The entire construction may therefore be built of rolledshapes and plates of standard size without producing substantially anyscrap.

In Fig. 2 the plate 6 at its connection with the bolster is interposedbetween the web of the bolster and an attached angle 8. In Fig. 3 theplate 6 is attached directly to the web of the bolster, and no attachedangle at this connection is shown. In Fig. 4 the plate 6 is interposedbetween the two members 3 3 of the bolster.

Within the scope of my invention as defined in the claims a skilledmechanic may modify the construction in various ways, since What I claimis 1. In combination with a bolster flanged at its lower side only, atension strut-plate secured directly to the web of the bolster andextending upwardly therefrom; substantially as described.

2. In combination with a bolster flanged at its lower side only, atension strut-plate secured directly to the web of the bolster,extending upwardly therefrom and secured to the car-floor; substantiallyas described.

3. A bolster having an integral flange at its lower edge only, and aparallel tension strut-plate secured to the upper portion of its web;substantially as described.

4. A car-sill, a bolster having an integral lower flange and a webextending above the sill, and a tension strut-plate secured directly tothe projecting portion of the bolster; substantially as described.

flanged member adjacent to its upper edge, of a tension strut-plateinterposed between the flanged member and the bolster and extendingupwardly therefrom and flanged braces connecting the bolster with theplate; substantially as described.

In testimony whereof I have hereunto set my hand.

ETHAN I. DODDS.
